Quantum information science - theory
= ASSESSMENT OF CURRENT RESULTS AND OUTLOOK ON FUTURE EFFORTS =
INTRODUCTION
The development of quantum information science (QIS) was initially
driven by theoretical work of scientists working on the boundary between
Physics, Computer Science, Mathematics, and Information Theory. In the
early stages of the development of QIS, theoretical work has often been
far ahead of experimental realization of these ideas. At the same time,
theory has provided a number of proposals of how to implement basic
ideas and concepts from link
building service quantum information in specific physical systems.
These ideas are now forming the basis for successful experimental work
in the laboratory, driving forward the development of tools that will
form the basis for all loan
modification future technologies which employ, control and
manipulate matter and radiation at the quantum level.
Today one can observe a broad and growing spectrum of theoretical
activities. Investigations include, to name just a few examples,
- basic concepts such as entanglement and decoherence,
- characterization and quantification of (two- & multi-party)
entanglement,
- novel quantum algorithms and communication protocols,
- capacities of noisy quantum communication channels,
- optimization of protocols for quantum cryptography,
- new computer models and architectures.
Another important class of theoretical work is concerned with
implementations of these abstract concepts in real physical systems.
In fact, many of these theoretical proposals have formed the starting
point as well as the guide for experimental work in the laboratories, as
is described in the other sections of this document. Last, but not
least, the transfer of concepts from quantum information theory to other
fields of physics such as condensed matter physics or quantum field
theory has proved fruitful and has attracted considerable interest
recently.
It is important to realize that these activities are often
interdisciplinary in nature and span a broad spectrum of research in
which the different activities are benefiting from each other to a large
degree. Thus it does not seem to be advisable to concentrate research on
too narrowly defined topics only. Theory groups in Europe have been
consistently delivered international leadership in the entire spectrum
of research (see more below). This has been facilitated by a flexible
and topically broad financing on European and national levels in the
past.
In the following we give a brief outline of the current status and
the perspectives of the main areas of quantum information theory.
